Professor and presenter, Chris Lintott, talks about his new book Our Accidental Universe; a tour of chance encounters and human error in pursuit of asteroids, pulsars, radio waves, new stars and alien life. Even with incredible technological developments, the major astronomical events of the past century are largely down to plain ol’ good luck; discovered not, as you might assume, by careful experiment, but as surprises when we have been looking for something else entirely. For instance, the...

The world’s oldest fossilised forest was uncovered in Somerset last week. We head to palaeobotanist, Dr Christopher Berry’s, lab at Cardiff University to learn about these cladoxylopsids. They lived 390 million years ago and although they are not the ancestors of today’s trees, they reveal some extraordinary evolutionary secrets. Also, Marnie speaks to Dr Chris Thorogood of the University of Oxford Botanic Gardens about his new book Pathless Forest: The Quest to Save the World’s Largest...

A recent study on how to get rid of microplastics in water sparked presenter Marnie Chesterton’s curiosity. When she turns on the tap in her kitchen each day, what comes out is drinkable, clean water. But where did it come from, and what’s in it? Dr Stewart Husband from Sheffield University answers this and more, including listener questions from around the UK. Is water sterile? Should I use a filter? And why does my water smell like chlorine? Also, new research indicates that bumblebees can...

Switzerland has submitted a proposal to create a United Nations expert group on solar geoengineering to inform governments and stakeholders. The idea was discussed at the UN Environment Assembly in Nairobi, Kenya, this week. Professor Aarti Gupta shares how, after tense negotiations, the different member states could not agree, and the proposal was withdrawn. Why is solar geoengineering a controversial issue? How would dimming the sun even work? And should we consider it a genuine option in...

Professor Ben Garrod guest presents. As a new 'meaty rice' is created and Fortnum & Mason launch a scotch egg made with cultivated meat that they hope to have on sale as early as next year, we investigate the world of laboratory-grown meat. Mark Post made the first ever synthetic meat in 2012 to the tune of £200,000. He tells us how these lab-grown meats are made and how, he thinks, they could play an important role in reducing greenhouse gas emissions and feeding a growing population....

The Gulf Stream, also known as the Atlantic Meridional Overturning Circulation (AMOC), is essential to stable global climate, and the reason we have moderate temperatures in Northern Europe. Now, a new modelling study suggests that this circulation could, at some point, be at a tipping point and collapse. We hear from one of the minds behind the model, post-doctoral researcher René van Westen from Utrecht University. But how likely is it that this will actually happen in the real world?...

As part of the Vesuvius Challenge, computer scientists have used machine learning to successfully reveal 2,000 characters from the Herculaneum scrolls. These artefacts were charred to a crisp following the eruption of Vesuvius in 79 AD. Papyrologist Federica Nicolardi has been translating the writings, and tells us what exactly has been deciphered. Following this week’s launch of NASA’s PACE satellite, NASA scientist Dr Susanne Craig tells us how the mission will be giving our planet a...

Are cyborgs now reality? Elon Musk certainly thinks so. His company, Neuralink, has successfully implanted one of its wireless brain chips in a human. Although billed as a breakthrough, they’re not the first to do it. In fact, similar devices have already been implanted, all with the aim of connecting our brains to computers with the aim of tackling complex neurological conditions. Joining Inside Science is neuroscientist and author, Dean Burnett. In this episode, Dean helps to break down the...

Hydrogen has long been touted as a potential wonder gas that could play a significant role in our race to net zero. Now, planning permission has been granted for the UK’s largest production hub of its kind, and one of the most advanced in the world. Located in Cheshire, it bills itself as a vital piece of Northwest England’s mission to help manufacturers in the region decarbonise their processes and support UK jobs. We speak to chemical engineer and the plant’s site manager, Richard Holden,...

As lava consumes homes on the Reykjavik Peninsula in Iceland, evacuated communities have been witnessing eruptions shifting and intensifying. We take a look at the latest science that’s helping teams on the ground accurately predict where the danger is coming from, helping people to stay safe. Our go-to volcanologist, Dr Evgenia Ilyinskaya, and her colleague, Professor Andrew Hooper, from the University of Leeds tell presenter Victoria about these new technological advancements, and ask the...

When Lois Pryce arrived at her boat in Berkshire, the area was already completely flooded. The only way to get to it was via a small pontoon. She is one of many across the UK that have been affected by the current floods, and is very familiar with the flood warning system accessible to the public. But how exactly does this system work? What information is taken into account? Marnie Chesterton speaks to Dr Linda Speight about flood forecasting, and the delicate balance of when to send out...

2024 is an exciting year for lunar exploration. For Inside Science this week Marnie Chesterton investigates the planned missions to the Moon over the next twelve months. It’s been more than fifty years since the last manned mission to the Moon was completed. But that’s about to change with NASA’s upcoming Artemis II mission. This will not only be the first manned lunar flyby of the Moon since 1972, but also the first mission to have a woman and person of colour on board. Reid Wiseman,...

We’re on board the RSS Sir David Attenborough for the vessel’s first big science season in the Antarctic, since it launched in 2020. It’s crewed by scientists involved in Project Biopole, a 5-year mission attempting to better understand carbon cycle at the poles. Nadine Johnston, a microbiologist with the British Antarctic Survey, joins Inside Science to talk about her work on copepods; zooplankton that build up huge fat reserves over the spring and summer months, then hibernate at 3000m...

COP 28, the largest climate summit in history, has drawn to a close. Marnie Chesterton examines some of the main stories to emerge from this lengthy conference. The way we look after our oceans, measures needed to ensure food security and an agreement to transition away from fossil fuel dependence were some of the big themes of the summit. The BBC’s climate reporter Georgina Rannard takes us through the final agreement. We hear from Glada Lahn, senior research fellow at international...

Vagrant birds are those that appear in locations where they are not usually found. They might have been blown off course by a storm or have been affected by changing weather patterns due to climate change. Although a treat for birders, these visitors can also have a big impact on their new environments as Victoria Gill finds out when she heads to Burton Mere Wetlands on the Dee Estuary with Dr Alexander Lees, reader in biodiversity at Manchester Metropolitan University. As former Prime...

Tunnels have been the focus of much attention this week as the war in Gaza continues and 41 workers were rescued in India, after 17 days trapped underground. Forensic geoscientists Jamie Pringle and Ruth Morgan explain the science behind identifying what’s beneath the surface, from above ground, and how you might work out what a tunnel is being used for. This winter, the Northern Lights are going to be the most spectacular they’ve been in twenty years. With the aurora borealis already...

Key scientific witnesses including former Chief Scientific Adviser Patrick Vallance and Chief Medical Officer for England Chris Whitty are called to the UK Covid-19 Inquiry. The BBC’s Jim Reed brings us his three key moments from the evidence heard over the past few days that have been dubbed “science week”. NASA has managed to let loose a tool kit in the Earth’s orbit -- and you can even see it in the night sky with binoculars. Lucinda King explains how this is possible and if space junk is...

An underground river of magma and thousands of tremors have been observed across the Reykjanes peninsula in Iceland. We speak to the scientists monitoring the Fagradalsfjall volcano who explain how this might be ushering in a new era of huge volcanic activity in the country. Sir Chris Whitty, Chief Medical Officer for England and Sir Patrick Vallance, former Chief Scientific Adviser to the UK government are due to appear at the Covid-19 Inquiry next week. It’s the next stage of the public...

Professor Saleemul Huq, director of the International Centre for Climate Change and Development in Bangladesh, has died. He was instrumental in pushing for a loss and damages fund for vulnerable countries affected by climate change. Last year’s COP27 climate conference made a pledge to set up this fund. But, as yet, there is not one in place. Marnie Chesterton speaks to BBC climate reporter Esme Stallard about Professor Huq’s legacy, and where the money will come from for a loss and damages...

PFAS chemicals, also known as forever chemicals, don’t break down in the environment. They can accumulate in the body and are found to have an array of harmful effects on human health. A major mapping project has revealed worryingly high levels of PFAS across thousands of sites in the UK. Experts are concerned that not enough is being done to reduce these chemicals from drinking water. They’re urging the government to re-evaluate current regulation. This week we dive into the properties of...

White phosphorous is an incendiary material and if it were to be used in any built-up civilian areas, the practice would violate international law. We find out what makes white phosphorus so dangerous, and we ask how easy is it to identify? Andrea Sella, professor of chemistry at University College London, grants access to his laboratory and conducts an experiment with this highly flammable and volatile substance. Whole words and phrases from crushed and carbonised scrolls can be read for...
